| Code Segment | Technical Meaning |
|---|---|
| JG120 | Indicates the specific bearing series (Reali-Slim) and size designation with a 12" bore. |
| C | Specifies the radial internal clearance group. |
| P | Denotes the bearing is pre-lubricated from the factory. |
| O | Signifies the presence of a sealed construction on both sides for contaminant exclusion. |
JG120CPO Bearing Structural Features & Performance Benefits
- Thin-Section Design: The 1-inch width and large diameter-to-cross-section ratio enable significant space and weight savings in complex assemblies without sacrificing performance.
- High Load Capacity: Constructed from chrome steel rings and balls, this bearing offers a high radial static load rating of 21,340 lbf and a dynamic load rating of 10,074 lbf, ensuring durability under demanding conditions.
- Sealed & Lubricated for Life: The integral seals protect against contaminants, and the factory-applied lubrication, suitable for a temperature range of -30°C to 110°C, provides long-lasting, maintenance-free service.
- Precision & Stability: The ABEC-1 tolerance class and brass cage contribute to smooth, low-noise operation and stable running accuracy, which is critical for precision applications.
JG120CPO Bearing Typical Application Areas
- Robotics and Automation Systems (for rotary joints and arms)
- Aerospace and Defense components (radar bases, gimbal systems)
- Medical Equipment (MRI scanners, surgical robotics)
- Semiconductor Manufacturing equipment (wafer handling robots)
- Precision Industrial Machinery requiring large, slim bearings
